The field of aging and geriatric nutrition highlights the critical role of diet in maintaining health and functionality in older adults. Nutritional strategies are designed to combat age-related challenges, such as muscle loss, weakened immunity, and cognitive decline. Adequate intake of key nutrients, including omega-3 fatty acids, antioxidants, and B vitamins, is emphasized to support brain health, reduce inflammation, and protect against chronic illnesses. Aging and Geriatric Nutrition also involves personalized dietary adjustments to accommodate conditions like dysphagia or dental issues that can affect food intake. By fostering awareness of the changing nutritional needs of aging populations, this discipline contributes to improved longevity, better health outcomes, and enhanced overall well-being.
